If the temperature of a confined gas is doubled at constant pressure, what change is observed?
A) The volume of the gas is decreased to 1/4 of its original value.
B) The volume of the gas is increased to twice its original value.
C) The density of the gas is doubled.
D) The velocities of the molecules are halved.
This question can't be answered correctly unless one knows if the temperature is in degrees C or in degrees Kelvin. Doubling from 25 C to 50 C is not the same thing as doubling from 100 K to 200 K.
